Iranian officials and lawmakers have intensified rhetoric calling for NPT withdrawal following the IAEA Board of Governors' September 2026 referral of Iran's safeguards noncompliance to the UN Security Council and amid ongoing restrictions on inspector access that began after 2025 military strikes on nuclear sites. A group of 130 parliamentarians issued a September 15 statement urging the legal process under Article X, citing attacks on facilities and perceived failures to protect Iran's rights, while a parliamentary spokesman described exit and nuclear doctrine changes as readily achievable. These statements align with prior threats and parliamentary proposals throughout 2026, including during the failed NPT Review Conference, yet Iran has maintained its membership without formal notice or implementation despite reduced IAEA cooperation. Traders assign an 87% probability against withdrawal before 2027, reflecting the short remaining timeline, the absence of a binding government decision, and the significant diplomatic, legal, and security implications of such a step.
